The synergistic mechanism of action of Dajianzhong decoction in conjunction with ketamine in the treatment of depression.

Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie September 2023 Chan Li, Jiping Zhang, Hanhe Liu et al.

Depression is a multifactorial syndrome with a variety of underlying pathological mechanisms. While ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist, exhibits a rapid antidepressant action in the central never system (CNS), the potential addiction and psychotomimetic adverse effects of ketamine limit its chronic use in clinical practice. Therefore, it is necessary to discover an...

A large‐scale open‐label trial conducted at electroconvulsive therapy (ECT) clinics has found that twice‐weekly dosing of ketamine was noninferior to three sessions a week of ECT in patients with treatment‐resistant major depression. Relapse rates during a 6‐month follow‐up period after the initial 3‐week treatment period were higher among patients receiving ECT than patients receiving...

Ketamine for depression: a potential role in requests for Medical Aid in Dying?

International Clinical Psychopharmacology September 1, 2023 Nicolas Garel, Michka Nazon, Kamran Naghi et al. 7 citations

Medical Aid in Dying (MAiD) is the act of a healthcare provider ending a patient's life, at their request, due to unbearable suffering from a grievous and incurable disease. Access to MAiD has expanded in the last decade and, more recently, it has been made available for psychiatric illnesses in a few countries. Recent studies have found that such psychiatric requests are rapidly increasing and...

Retigabine promotes ketamine's antidepressant effect in the forced swim test in male and female C57BL/6J mice.

Pharmacology, Biochemistry, and Behavior September 1, 2023 Yixue Qin, Haoxuan Li, Yuqi Zhang et al. 6 citations

Ketamine has been increasingly used as a rapid-onset antidepressant in specific clinical settings. However, as a psychedelic reagent, the potential of physical and psychological dependence limits its clinical use. Here, we added retigabine, a KCNQ channel opener, as an adjunctive treatment to observe its effect on ketamine's antidepressant property in a forced swim test in both male and female...

American Journal of Psychiatry and Neuroscience August 17, 2023 Marcus C. Rosenhagen, Julien Elowe, Alberto Forte et al.

Ketamine, initially developed as a safer alternative to phencyclidine, has emerged as a groundbreaking treatment in psychiatric practice. It gained popularity after its approval by the FDA in 1970 for its analgesic properties and ability to induce altered consciousness while maintaining vital functions. In the 1990s, researchers discovered its rapid and potent antidepressant effects, especially...

The effect of ketamine on affective modulation of the startle reflex and its resting-state brain correlates

Scientific Reports August 16, 2023 Zümrüt Duygu Sen, Tara Chand, Lena Vera Danyeli et al.

Ketamine is a rapid-acting antidepressant that also influences neural reactivity to affective stimuli. However, the effect of ketamine on behavioral affective reactivity is yet to be elucidated. The affect-modulated startle reflex paradigm (AMSR) allows examining the valence-specific aspects of behavioral affective reactivity. We hypothesized that ketamine alters the modulation of the startle...
